The non-HVM argument will always exist, and could actually get worse
if lots of vendors start shipping with embedded hypervisors, such that
your 'real' OS is already virtualized behind your back. That said I do 
agree with you - we're still better off killing/deprecating kqemu and 
using any spare effort to improve nested-SVM/VT support which is a more 
useful long term feature.
